Mitsubishi Electric MR-J2S-20A1-PE042 Servo Amplifier

The Mitsubishi Electric MR-J2S-20A1-PE042 is an AC servo drive amplifier that controls low-power servo motors in industrial automation, delivering precise speed, torque, and position control for CNC machines, small robotics, indexing tables, and automated assembly equipment. It is part of the MR-J2S-20A1 series with an approximately 200 W class rating, 100–120 VAC single‑phase input, and about 5 A output current in a closed‑loop servo control scheme using encoder feedback. Compatible with Mitsubishi HC-KFS, HC-MFS, and HC-SFS motors, it supports high‑speed SSCNET serial communication, auto‑tuning, positioning control, dynamic braking, forced‑air cooling, and panel mounting, with 0–55 °C operating temperature, -20 to 65 °C storage, and overcurrent, overvoltage, and overheat protection.
